Six carats of round brilliant perfection — the 6.2ct DEW White Moissanite Round Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified. At 6.2ct DEW in the round brilliant cut, this ring delivers a stone approximately 12mm in diameter — producing brilliant sparkle and coloured fire at a scale that represents the most visually compelling round moissanite in the everyday-statement category.
A 6.2ct DEW round moissanite is approximately 6× the size of the average US engagement ring and significantly larger than most celebrity engagement rings. In 2026, large moissanite engagement rings have become a widely accepted and increasingly popular choice — particularly among buyers who prioritise visual impact and value over stone origin. The conversation around moissanite has shifted substantially: it is no longer positioned as a "diamond alternative" but as its own premium gemstone category with superior optical properties and ethical provenance. A 6ct round moissanite engagement ring in 2026 is a bold, informed, fashionable choice.
Round brilliant moissanite photographs exceptionally well across all photography types. In natural light photography (the most common engagement ring photography context), the stone produces strong brilliance — bright, clean white sparkle — that reads clearly even in phone camera images. In professional photography with controlled lighting, the fire (rainbow dispersion) becomes highly visible and creates the coloured-sparkle images associated with fine jewelry editorial content. At 6.2ct, the stone is large enough that its light performance is clearly visible even in casual, handheld social media photography. This ring will produce excellent engagement ring content for Instagram, TikTok, and Pinterest.
